The practice of not drinking for the entire month of January -- staying "dry" -- usually in response to over-consumption during the holidays. Avoiding alcohol for the month can be seen as a form of New Year's resolution intended to cleanse the liver, promote a more healthy lifestyle, atone for sins of the past, etc. Drynuary usually results in an increase in seeing movies, drinking sparkling water in bars, and hanging out in diners drinking coffee on Saturday nights.

Usually followed by an ill-advised reentry into heavy boozing on February 1st without realizing how badly your tolerance has suffered.

1) After Holiday Party Season, my liver feels like I used it for a speedbag. Time to celebrate Drynuary!

2) Oh, man, I'm so hungover! Drynuary ended yesterday, so I got hammered on two beers.
